Intravitreal injection has become an indispensable tool for delivering drugs at therapeutic levels to the posterior segment with least systemic side effects.[1] Iatrogenic crystalline lens injury is a rare complication mainly caused by the improper method of administration resulting in contact or penetration of the lens by the needle tip[2] [Figure 1]. The needle should puncture the pars plana corporis ciliaris 3.5–4 mm posterior to the limbus with an oblique insert angle directed at the optic nerve.[1] Precise selection of needle entry points and angles, adequate anesthesia, stable globe fixation, and small-size injection needles are important to avoid such complications.
